For some people, Skype has been an important part of their daily lives. If they can’t sign in to their account, their day can easily be ruined. One of the best solutions to this problem is reinstalling the program. Just uninstall Skype, restart your PC, then try to install it once again.

On the other hand, you can always create a System Restore point you can go back to in case something goes wrong.

Fourth Method: Using a different device or using Skype for Web

There might be issues with your desktop Skype client, which is why you’re having trouble signing into your account. You can determine if this is the case by trying Skype for Web. Sign in to your account, then check if the error message still appears.

Your firewall or antivirus software can also interfere with Skype. There are users who reported problems with Eset Smart Security.

If removing the antivirus program fixes the error, you might want to switch to different security software. One of the most reliable tools you can try is Auslogics Anti-Malware.
